However, data are lacking on whether monotherapy with AHP can be effective in CHB patients with alanine aminotransferase (ALT) levels less than 2 times the upper limit of normal (ALT<2ULN) and early liver fibrosis (F ≤ 2).
Aim Of The Study: We aimed to investigate whether monotherapy with AHP improves liver histology in these patients.

The aim of this study was to determine if microRNA (miRNA) expression is different among chronic hepatitis B (CHB) patients with early liver fibrosis classified according to traditional Chinese medicine (TCM) syndromes. Eighteen CHB-fibrosis patients and 12 CHB patients without fibrosis were enrolled. The CHB-fibrosis group included 9 patients with the TCM syndrome of Ganyu Pixu Xueyu (GYPXXY), characterized by liver stagnation, spleen deficiency, and blood stasis, and 9 patients with the TCM syndrome of Qixu Xueyu (QXXY), characterized by deficiency of qi, blood, and blood stasis.

Controlling target gene expression is a vital step in the procedure of gene therapy upon acute lung injury (ALI). Excessive activation of nuclear factor-kappa B (NF-κB) has been the key point of the inflammation overwhelming process in onset of ALI. We designed and tested a variety of plasmid named pHSP70/IκBαm which conditionally carries a mutant inhibitor of kappa B (IκB) transgene to regulate the activity of NF-κB signaling pathway in its response to an inflammatory stimulus that causes acute lung injury.

However, it does not provide good benefits for AIH patients because of its serious side effects. Therefore, more and more AIH patients prefer to seek for traditional Chinese medicine (TCM) to manage their symptoms and reduce the side effects of steroids in China.

Matrine is one of the main active components of Chinese herb Sophora flavescens Ait (Kushen), which has been demonstrated to be effective in suppressing inflammation. The aim of the present study is to investigate the effect of matrine on LPS-induced lung injury. Lung injury was assessed by histological study and wet to dry weight ratios, as well as cell count and protein content in bronchoalveolar lavage fluid.

Background: Hypoxic pulmonary vasoconstriction may lead to pulmonary hypertension, but the underlying mechanisms of persistent vasoconstriction are still unclear. There is evidence that pulmonary inflammation contributes to the abnormalities of function in the pulmonary artery (PA) following chronic hypoxia exposure. Macrophage migration inhibitory factor (MIF) is an important pro-inflammatory cytokine, and we found that expression of MIF was increased in the smooth muscle of PA from hypoxic pulmonary hypertensive rats.

Sodium tanshinone IIA sulfonate (STS) has been observed to reduce lung edema from lipopolysaccharide (LPS)-induced lung injury. In this study the authors investigated whether STS attenuates seawater aspiration-induced acute pulmonary edema, and examined the effects of sodium-potassium adensosine triphosphatase (Na(+),K(+)-ATPase) on it.

Objective: To explore the effects of tanshinone IIA on the activity of aquaporin-5 (AQP5) in human alveolar epithelial cells (A549) after seawater exposure and its possible mechanism.
Methods: Routinely cultured A549 cells were divided into different groups according to different content of seawater: blank control group, 15%, 25%, 50%, 75%, 100% seawater groups; they were divided into different groups according to the duration of exposure to 25% seawater: blank control group, 1, 4, 8 hours groups; they were also divided into different groups according to concentration of tanshinone IIA and exposed to seawater for 4 hours: blank control group, 25% seawater group, 25, 50, 75, 100 μg/ml tanshinone IIA intervention groups. The expressions of AQP5 were respectively assayed by Western blotting and immunohistochemistry.

Antivascular therapy provides a promising method for anticancer therapy. But targeting to gastric cancer vessels is nonselective due in part to the lack of specific cell-surface receptors identified on target vascular cells. Herein we used in vivo screening of phage displayed peptide library to identify some peptides that bind selectively to endothelial cells of human gastric cancer rather than nonendothelial cells.
